Enter a code to go to a specific page - php

I want to use an idea that I have seen on another website where I enter a "keyword", press Enter, and it then takes the client to a specific page or website.
I have seen something like this on http://qldgov.remserv.com.au, On the right side there is a field called "My Employer", type in "health" for example and you will be provided with relevant content.
Essentially I have client branded mini sites where we want to assign a "keyword" for each client brand so all of their employees will be able to go to their site entering this one keyword without all of them having individual logins. I want to be able to link to a URL that I can define in some manner.
I have looked at the source code of the site mentioned above and see they are using a form but I am not sure how they have assigned the keywords or if its even possible to do this without a database or anything like that. Trying to keep it as simple as possible as I am not a PHP/Java expert by any means.
Any help would be appreciated, even if its not code but an idea of the direction I need to go in to make this work. Thanks in advance!! :-)

The easiest way in my eyes would be to define an array that contains all of the keywords and respective urls client side (in JS). For example:
​var array = { 'health' : '/health.php', 'sport' : '/swimming.php' };
You would then get the user input on onSubmit and if it exists modify the window.location appropriately.
if ( array[user_input] !== undefined ) {
window.location = array[user_input];
}
else {
alert ( 'not found' );
}
If the user supplied health they will be redirected to /health.php, if they supply sport they will be redirected to /swimming.php (JSFiddle). Alternatively you can use server-side (PHP, JAVA) to handle the request but this may not be worth the effort.
Goodluck.

By using php (rather than javascript), you're not relying on javascript + making it seo friendly.
Firstly you're going to need either some sort of database or a list of keywords/urls
$keywords = array('keyword1' => 'path/to/load.php', 'another keyword' => 'another/path');
Then you'll need a basic form
<form action="loadkeyword.php">
<input name="query">
<button type="submit">Go</button>
</form>
Then in loadkeyword.php
$keywords = array('keyword1' => 'path/to/load.php', 'another keyword' => 'another/path');
$query = $_GET['query'];
if (isset($keywords[$query])) {
$url = $keywords[$query];
header("HTTP/1.0 301 Moved Permanently");
header('location: '.$url);
exit;
} else {
header("HTTP/1.1 404 Not Found");
die('unable to locate keyword');
}
If you have a large list of keywords, I would suggest using a database instead of an array to keep track of your keywords.

The site you link to is doing it server-side, either via a keyword-list that matches content or a search function (I suspect the latter).
There are a few different ways you could achieve your goal, all of them to do with matching keywords to content and then redirecting, either with an array, a list, or a database - the principle will be the same.
However, I would respectfully suggest this may not be the best solution anyway. My reasoning is that (based upon the example you give) you're effectively making your users guess which keyword matches which minisite (even if you have many keywords for each site). Why not just have some kind of menu to choose from (i.e. a selector with a list of minisites)?

how to check if bookmarks exist in html document

I've just designed my first form in HTML and a PHP page to display the results. In the form the user inputs some codes in response to some questions, a bit like a multiple choice, so for example, these are "ABC". The PHP page displays the code to the user as a link, which when clicked will go to a bookmark (a link within the same page) with the ID #ABC. This was achieved with simple manipulation of the PHP variable as follows:
<?php
$code = "ABC"
$part1 = '<a href="mywebpage.php#';
$part2 = '">Go to this code</a>';
$string = $part1.$code.$part2;
echo $string;
?>
(i.e. Link in the page says "go to this code" and when clicked will go to section with bookmark ABC)
This all works fine, but I simply need to know if there is a way of error trapping so that if a bookmark does not exist for the code entered, a message can be displayed to the user instead? Can this be done using the PHP variable, or do I need to use JavaScript? One work around may be to search the web page for the ID "#ABC'. Is it possible to do this? Another option would be to store an array of valid codes on the server then query this before setting the bookmark, but I want to keep it as simple as possible. Any help appreciated, thanks.
What you call a "bookmark" we call a hash. And when you say "go to a bookmark" you mean a hash change. Hash changes do not make an additional request to the server, it is all handled on the client-side, therefore this must be done with JavaScript and not PHP.
So let's just do some simple JavaScript on hash change window.onhashchange that will search for an element with that ID and if it's not found alert something.
window.onhashchange = function(){
if(!document.getElementById(location.hash){
alert("not found");
}
}

How to make a webpage retain variables from form?

Sorry if I'm duplicating threads here, but I wasn't able to find an answer to this anywhere else on StackOverflow.
Basically what I'm trying to do is make a list in which variables entered in a form by a user can be kept. At the moment, I have the code which makes this possible, and functional, however the variables entered in the form only appear on the list after the user hits submit... As soon as I refresh the page or go to the page from somewhere else, the variables disappear. Is there any way I can stop this from happening?
Edit: here are the codes:
//Page 1
<?php
session_start();
$entries = array(
0 => $_POST['signup_username'],
1 => $_POST['signup_email'],
2 => $_POST['signup_city']);
$entries_unique = array_unique($entries);
$entries_unique_values = array_values($entries_unique);
echo "<a href='Page 2'>Link</a>";
$_SESSION['entries_unique_values'] = $entries_unique_values;
?>
//Page2
<?php
session_start();
$entries_unique_values = $_SESSION['entries_unique_values'];
foreach($entries_unique_values as $key => $value) {
$ValueReplace = $value;
echo "<br /><a href='http://example.com/members/?s=$ValueReplace'>" . $value . "</a><br/>";
}
?>
Your question is really quite vague. the answer depends on how much data you have to store, and fopr how long you need it to exsist.
By variable I assume you mean data the user has entered and that you want to put into a variable.
I also presume that the list of variables is created by php when the form is submitted.
Php will only create the variable list when the form is submitted as php is done entirely on the server, therefore you will not have or see the variables until the form is submitted.
if you wanted to be able to see the list as it is being created you could use javascript then once you have you php variables the javascript list isn't necesary.
each time you request a php page wheather it is the same one or not the server generates a totally new page, meaning all unhardcoded variables from previous pages will be lost unless you continually post the variables around the pages the server will have no memory of them.
You have a few viable options.
) keep passing the user created variables in POST or GET requests so each page has the necesary info to work with. Depending on the situation it might or might not be a good idea. If the data only needs to exsits for one or two pages then it is ok, but bad if you need the data to be accessable from any page on your web.
2.) start a session and store the variables in a session. Good if the data only needs to be around while the user is connected to the site. but will be lost if user close window or after a time.
3.) place a cookie. not a good idea but ok for simple data.
4.) create a mysql database and drop the variable info in there. great for permanent data. this is how i always complex user data.
just a few ideas for you to look into as it is difficult to see what you really mean. good luck.
use PHP session or store variable values in Cookies via JS or using PHP. It would be nice if you show your working codes :)
Your idea is fine, however you just need to add a little condition to your Page 1 that only set your SESSION values when POST is made, that way it will keep the values even if you refresh. Otherwise when you visit the page without a POST those values will be overwritten by blank values, which is what you are seeing now. You can modify it like
<?php
session_start();
if(isset($_POST["signup_username"]))
{
$entries = array(
0 => $_POST['signup_username'],
1 => $_POST['signup_email'],
2 => $_POST['signup_city']);
$entries_unique = array_unique($entries);
$entries_unique_values = array_values($entries_unique);
$_SESSION['entries_unique_values'] = $entries_unique_values;
}
echo "<a href='http://localhost/Calculator/form2.1.php'>Link</a>";
?>
You could use JavaScript and HTML5 local storage.

Get an id then put it into a href

I'm a bit new to this so sorry if this has been covered already but i'm going around in circles searching.
I've had a look around learn t how to edit htaccess and use the get function, I then even found a plugin called redirection that did similar.
What I would like to do is if I have a URL http://example.com/file.php?id=blue
is to grab the id which is "blue"
then in a href link dynamically add it to the end of another url
Link Example
If someone could help show me or point me in the right direction on how to get the id blue and add it into a href that would be great.
Many Thanks
You have to use $_GET. People might be dicks about it here - but I had a hard time when I was first learning to program too. You'll get it, don't worry.
This is how get works (at least, all you need to know about how it works):
if you have the file index.php
if you add a query string to the end of it like index.php?id=1
You can access id=1 by doing the following in your code:
$id = $_GET['id'];
Similarly if the query string contains the following index.php?id=1&page=5&par=3&club=putter&upnext=tigerwoods
On the left hand of the equal sign is the Key(id, page, par, club, upnext) and on the right side their value(1,5,3,putter,tigerwoods)
One thing to remember is that when retrieving numbers from the query string they will always be of the string type, so you cant do something like
if ( $_GET['page'] === 5 )
you'll have to do
if ( $_GET['page'] == 5 )
and to echo it into a link:
$club = $_GET['club'];
if ( $club == 'NRA' ) {
echo "Gun Show";
echo 'Buy tickets to my gunshow ^^';
}
Hope this helps!
You can also do things like set your website up so that it has one template and use the $_GET parameter to determine which files to include into the content sections of the site via a switch command. I do this, but not across my whole site. For my user control panel, I do this to simply include only the file necessary (change email, update password, delete account, update profile, etc)
Cah'piche?
Use the $_GET parameter.
YAY!!

pass a value from one page to another outside querystring and without javascript?

One solution to automatically building navigation for a site is by scanning a folder for documents like this:
foreach(glob('pages/*.pg.php') as $_SITE_NAV_filePath):
$_SITE_NAV_filePath = explode('.pg',pathinfo($_SITE_NAV_filePath,PATHINFO_FILENAME));
$_SITE_NAV_fileName = $_SITE_NAV_filePath[0];
$_SITE_NAV_qv = preg_replace('/([A-Z])/','-$1',$_SITE_NAV_fileName); $_SITE_NAV_qv = trim($_SITE_NAV_qv,'-');
$_SITE_NAV_name = preg_replace('/([A-Z])/',' $1',$_SITE_NAV_fileName);
?>
<li><?=$_SITE_NAV_name?></li>
<?php
endforeach;
This code will turn "AnAwesomePage.pg.php" into a menu item like this :
<li>An Awesome Page</li>
This might be bad practice (?).
Anyway; I don't use this method very often since most of the time the sites have a database, and with that comes better solutions...
But my question is this:
Is there a way to prefix the filename with a integer followed by and underscore (3_AnAwesomePage.pg.php), for sorting order purposes, and pass it somehow to the destination page outside of the querystring and without any async javascript?
I could just explode the filename once again on "_" to get the sort order and store it somewhere, somehow?
This is the code for handeling the page query request:
$_SITE_PAGE['qv'] = $_GET['page'];
if (empty($_SITE_PAGE['qv'])){ $_SITE_PAGE['qv'] = explode('-','Home'); }
else { $_SITE_PAGE['qv'] = explode('-',$_GET['page']); }
$_SITE_PAGE['file'] = 'pages/'.implode($_SITE_PAGE['qv']).'.pg.php';
This code turns "An-Awesome-Page" back into "AnAwesomePage.pg.php" so it's possible to include it with php.
But with a prefix, it's not so easy.
The probliem is; Now there's no way to know what prefix number there was before since it has been stripped away from the query string. So I need to send it somehow along in the "background".
One very bad solution I came up with was to transform the navigation link into a form button and just _POST the prefix interger along with the form. At fist it sounded like a nice solution, but then I realized that once a user refreshes their page, it didn't look very good. And after all, that's not what forms are for either...
Any good solutions out there?
Or some other and better way for dealing with this?
There are two ways to keep that number saved, you can use cookies or php session variables.
But in this case, if user first enter the url in the browser or in a new browser, then he should be taken to default number.
Like you have:
1_first-page.php
2_first-page.php
3_first-page.php
If user enter the url like: domain.com/?page=first-page, you have to take him to 1_first-page.php to any number which you want to be default.

Vaildate a Zip code against a list

I want to have a form on my intranet site... basically we are a home improvement company and have a list of bad area codes that we do not do business in ... IE list of bad zips 19020 19021 etc are bad so if they are I want it to return with a popup which says bad area ... if it is not on the list I want it to say Good Area
You haven't given too much information, so what follows is a very general solution. One way to approach this is to have two maps called badZips and goodZips:
var badZips = {
"19020": true,
"19021": true
...
};
var goodZips = {
"90210": true,
...
};
Then in your form-validation function, you can do:
if(badZips[zip]) {
alert("You entered a bad zip code");
}
else if(goodZips[zip]) {
alert("You entered a good zip code");
}
else {
alert("That zip code is not recognized");
}
Actually creating the maps depends on how your webapp is set up. How do you store the zips - is it in the database? Or have you hardcoded it?
Using apache, install geoIP. Echo their zipcode into a javascript function, which compares to a black-list you created.
http://www.maxmind.com/app/ip-location
Your functional requirements are pretty simple but you didn't really mention what setup you have. Do you want this functionality to happen on a form? What are you going to code with? Do you have a database? Based on the tags you've used I'll just assume that you don't have a database.
Basically you can have a list of area codes and a flag for each to indicate if it's a bad or a good code. You can keep this list in a multi-dimensional array in PHP as static data (http://www.webcheatsheet.com/PHP/multidimensional_arrays.php).
So it might look something like:
<?php
$areaCodes = array( array('aCode'='19020','aFlag'=>true),
array('aCode'='19021','aFlag'=>true),
array('aCode'='19022','aFlag'=>false)
);
?>
When you need an area code to be validated, just do a search in the array and check the flag to see if it's a good code or a bad code.
Store the zip codes in an array, then check if the given zip is in the array.
<?php
$BadZip = array("19020", "19021");
if (in_array($Zip, $BadZip))
{
echo "Bad Zip code!";
}
?>
If in_array returns true, then the zip code is in the list of bad zips.
Alternatively you could use the same method with a list of good zips.
